Abstract. New experimental data on planar channeling of 255 MeV electrons in a 0.74 µm Si Half-Wave Crystal (HWC) obtained at SAGA-LS facility are presented. The computer simulation showed that the angular distribution of electrons after penetration through the HWC revealed the number of unknown before peculiarities is connected with specific electron trajectories in HWC. These specific trajectories lead to specific radiation, the properties of which are analyzed.

“…6 the veer of 50 calculated) trajectories in Si HWC look like the arc of a circle, let us compare radiation from electrons channeled in HWC along those trajectories with radiation spectrum from an electron moving in an arc [15]. One can suggest that an elections moves with constant angular velocity x a along the arc of circle with the radius R and its penetration time s ¼ L=bc ¼ 2n=x a .…”

My family and friends, who had been helping me throughout all these years of work deserve special thanks. Thank you. i ii ResumoConsideramos as características da radiação síncrotron (RS) noâmbito da teoria quântica. Para simplificar a descrição teórica do processo de radiação restringimosà consideração da emissão deúnico fóton. Para transições quânticas arbitrárias, as distribuições espectrais e angulares da potência da RS são dadas de forma analítica exata. Tratamos separadamente partículas escalares (bósons) e com spin /2 (elétrons). Atenção especialé dadaàs transições particulares, a saber, as transições ao primeiro estado excitado e estado fundamental.É mostrado que os componentes de polarização linear da radiação de elétron se trocam em relaçãoà orientação de spin quando o elétron passa para o estado fundamental.Este fato pode ser considerado como uma comprovação analítica para a presenca de π-componente da radiação quântica no plano de movimento.Analisamos minuciosamente a radiação emitida pela partícula fracamente excitada. Várias funções são introduzidas para descrever a evolução dos perfis de distribuições angulares para sistemas de dois e três níveis. Para transições quânticas do primeiro estado excitado ao estado fundamental a análise comparativa da radiação de bósons e elétronsé realizada, e isso ajuda a estimar a influência de spin e sua direção sobre as características da RS. A radiação de elétrons não polarizadosé considerada separadamente. Observando o comportamento dosângulos efetivos,é fácil perceber a inconsistência da conclusão clássica bem conhecida sobre a concentração de radiação ultra-relativista total no plano do movimento.Mostramos que osângulos efetivos da radiação quântica tendem aos valores finitos e não desaparecem na região ultrarelativista.Uma revisão breve da teoria clássica inclui a introdução do conceito novo, istoé a n-parte do espectro.A fim de encontrar um análogo clás...
